1. A short bus that has been souped up, with engine modifications, chrome, spoiler, sidepipes, etc. In extreme cases, a short bus can be outfitted with the sort of suspension and oversize wheels seen on a monster truck, then entered in competitions. A very unusual sight.
1. Check out that souped up short bus. It's been modified to go fast and look cool. You don't see one of those everyday

Someone who has graduated from the short bus ( middle school or high school.) and is still a fucking idiot. even if you've never been on the short bus you are not exempt from being classified as a Short Bus Alumni. (As long as your stupid or do stupid shit or as kind as your an idiot and do idiotic shit you can proudly claim your a Short Bus Alumni
If anyone does something remotely stupid or any action devoid of intelligence, the proper response should be " Are you a Short Bus Alumni?". It could also be use to say that one is not stupid or devoid of intelligence " At least your not a Short Bus Alumni"
